To do this, use Transaction SFW5, and look at the **Planned Status** column. If these business functions aren’t activated, activate them by choosing the checkbox in the **Planned Status** column, followed by choosing **Activate Changes** from the top menu bar. ![Activating Business Functions](https://blog.sap-press.com/hs-fs/hubfs/2222_05_003.png?width=928&height=459&name=2222_05_003.png) **Note:** If the contact person of a customer or a vendor is also to be synchronized with the contact person of a business partner, then the **VENDOR\_SFWS\_SC1** and **VENDOR\_SFWS\_SC2** checkboxes must be activated under business function **CA\_BP\_SOA**.   Next, carry out some preparatory activities in Customizing via **SAP IMG >** **Cross-Application Components >** **Master Data Synchronization >** **Synchronization Control >** **Preparatory Steps for Master Data Synchronization** to ensure that correct settings for using the CVI are in place. Under **Structure** (see below), choose **Preparatory** **Steps for Synchronization Control**, and then choose the corresponding help documentation. In the documentation itself, choose the **synchronization processes** hyperlink on the right side of the screen. ![Synchronization Control](https://blog.sap-press.com/hs-fs/hubfs/2222_05_004.png?width=1007&height=517&name=2222_05_004.png)   In the screen that appears (shown below), enter “MDSV\_CTRL\_OPT” in the **Table/View** field, and then choose **Maintain**, which will bring up the second figure. ![Maintain Table](https://blog.sap-press.com/hs-fs/hubfs/2222_05_005.png?width=841&height=412&name=2222_05_005.png)   On the next screen, the **Synchronization Options** marked with the relevant checkbox in the figure below must be present: a **Synchronization Option** shows which source synchronization object ( **Source Object**) can be merged with which target synchronization object ( **Target Object**). In this case, ensure the four entries marked with the checkbox are present in the SAP ERP system, as follows: - **BP: CUSTOMER** - **BP: VENDOR** - **CUSTOMER: BP** - **VENDOR: BP** ![Synchronization Options](https://blog.sap-press.com/hs-fs/hubfs/2222_05_006.png?width=849&height=498&name=2222_05_006.png) The queues must be registered and activated for background processing of the synchronization processes. Choose the **queuep rocessing** hyperlink so that the **qRFC Monitor** screen shown below appears.   ![qRFC Monitor](https://blog.sap-press.com/hs-fs/hubfs/2222_05_007.png?width=1006&height=464&name=2222_05_007.png)   Choose **Registration** from the top menu bar, enter the name for each of the following four queues followed by an \*, and activate and register them by choosing **Continue** (see next figure): - MDS\_BUPA\_CUST\* - MDS\_BUPA\_VEND\* - MDS\_CUST\_BUPA\* - MDS\_VEND\_BUPA\* ![Queue Registration](https://blog.sap-press.com/hs-fs/hubfs/2222_05_008.png?width=654&height=360&name=2222_05_008.png)   Now the queues shown in the next figure should be available.   ![Registered Queues](https://blog.sap-press.com/hs-fs/hubfs/2222_05_009.png?width=863&height=281&name=2222_05_009.png)   Finally, use menu path **SAP IMG >** **Cross-Application Components >** **Master Data Synchronization >** **Synchronization Control >** **Synchronization Control >** **Synchronization Objects** to check whether the objects business partner (**BP**), **VENDOR**, and **CUSTOMER** are defined as synchronization objects in the system (see final figure). The **Block Size** for the background processing of the mass synchronization is part of an initial synchronization. The **Extractor Class** (not shown) is for the synchronization object if the object is used as a source object within a synchronization process. Be sure to also choose the **Platform** checkbox for (**BP**), **VENDOR**, and **CUSTOMER** as this setting will be needed during automated customizing. ![Synchronization Objects](https://blog.sap-press.com/hs-fs/hubfs/2222_05_010.png?width=927&height=546&name=2222_05_010.png)     Editor’s note: This post has been adapted from a section of the book *[Business Partners in SAP S/4HANA: The Comprehensive Guide to Customer-Vendor Integration](https://www.sap-press.com/business-partners-in-sap-s4hana_5468/?utm_source=sappressblog&utm_medium=referral&utm_campaign=Blogs&utm_term=2222_chapter5&utm_content=2222)* by [Jawad Akhtar](https://www.linkedin.com/in/jawadakhtar/).
